Does the alkaline solution freeze when the temperature drops?

Does the alkali solution line of the liquefied gas desulfurization system require heat tracing? Is heat tracing needed for the static alkali tanks? What is the appropriate temperature to maintain?
Heating is usually provided; at low temperatures, sodium hydroxide will crystallize and precipitate. Moreover, without a stirrer, the concentration in the alkali tank becomes uneven, which is problematic
Yes, at low temperatures, highly concentrated alkaline solutions tend to crystallize easily
Yes, it crystallizes when the concentration is high.
Can emulsification occur at higher temperatures?
It is related to concentration; at high concentrations, crystallization occurs, and heat retention is required.
All the liquid caustic pipelines in our company are insulated; we are located in Shandong!
We don’t have heating here; piping tends to corrode when heated. The alkali solution line that is shut down in winter will crystallize
The pipeline does not need to be insulated, but it must be thoroughly purged
Heating is required, as sodium hydroxide will crystallize at low temperatures.
